Representation from the Boardroom to the Courtroom

Ogborn Mihm Quaintance, Prof. LLC is a Sioux Falls, SD law firm for personal injury, business litigation, commmercial law and legal malpractice.

What We Do

We assess, prepare, and present each case individually based on its unique facts and
circumstances; there is no template for the personalized representation we provide.

Our office provides hope for seriously injured people. We have the experience and the fortitude to fight for our client’s wellbeing and rights. Because this takes time and resources, we limit our representation to those clients who have serious injuries from a collision that have a significant impact on a person’s life.
